The given quadratic equation is :
[tex] x^{2}+2=102 [/tex]
We have to solve the given quadratic equation for the value of 'x'.
[tex] x^{2}+2=102 [/tex]
[tex] x^{2}=102-2 [/tex]
[tex] x^{2}=100 [/tex]
[tex] x=\sqrt{100} [/tex]
x= [tex] \pm 10 [/tex]
So, the value of 'x' in the given quadratic equation are 10 and -10.
